NAME
Catalyst::Model::DBI - DBI Model Class
SYNOPSIS
# use the helper to create a model for example
perl script/myapp_create.pl model MyModel DBI dsn username password
# lib/MyApp/Model/DBI.pm
package MyApp::Model::DBI;
use base 'Catalyst::Model::DBI';
__PACKAGE__->config(
dsn => 'DBI:Pg:dbname=mydb;host=localhost',
username => 'pgsql',
password => '',
options => { AutoCommit => 1 },
loglevel => 1
);
1;
# or load settings from a config file via Config::General for example
# in your myapp.conf you could have
name MyApp
dsn "DBI:Pg:dbname=mydb;host=localhost"
username pgsql
password ""
AutoCommit 1
loglevel 1
# note that config settings always override Model settings
# do something with $dbh inside a controller ...
my $dbh = $c->model('MyModel')->dbh;
# do something with $dbh inside a model ...
my $dbh = $self->dbh;
#do something with DBIx::Connector connection inside a controller ...
my $connection = $c->model('MyModel')->connection;
#do something with DBIx::Connector connection inside a model ...
my $connection = $self->connection;
DESCRIPTION
This is the "DBI" model class. It has been rewritten to use
DBIx::Connector since it's internal code that deals with connection
maintenance has already been ported into there. You now have two options
for doing custom models with Catalyst. Either by using this model and
any related modules as needed or by having your custom model decoupled
from Catalyst and glued on using Catalyst::Model::Adaptor
Some general rules are as follows. If you do not wish to use
DBIx::Connector directly or DBI and setup connections in your custom
models or have glue models, then use this model. If you however need
models that can be re-used outside of your application or simply wish to
maintain connection code yourself outside of the Catalyst, then use
Catalyst::Model::Adaptor which allows you to glue outside models into
your Catalyst app.
METHODS
new Initializes DBI connection
$self->connection
Returns the current DBIx::Connector connection handle.
$self->dbh
Returns the current database handle.
$self->connect
Connects to the database and returns the handle.
